If you open up your hood, you can probably locate your Audi S4 radiator with ease. The S4 radiator is a large metal rectangular device with a small round cap to one side of the top, situated near the front end of your engine bay. Your Audi S4 radiator has two radiator hoses connected to it; an upper and a lower.

There will also be a cooling fan on one side of the S4 radiator, usually between the radiator and the engine block. Your Audi S4 radiator is the primary component of your engine's cooling system.

Temperatures under your hood can reach quite high, and all that heat is a threat to the moving parts of your engine. The job of the S4 radiator is to keep the coolant circulating through the engine from boiling, so it can continue to do its job. As coolant travels through your engine, it enters the Audi S4 radiator through the intake hose. Once inside the S4 radiator, the superheated fluid is cooled by the radiator fan, and then returned to the engine through the outtake hose. Problems can develop with your Audi S4 radiator if the hoses are worn or the connections are loose, which can cause leaks. Also, your S4 radiator can become blocked or plugged over time if it is not flushed and cleaned regularly according to the manufacturer's guidelines. Holes in your Audi S4 radiator can develop resulting from rust, corrosion, or front-end impacts.
